1:The following is part of a business plan created by the management of the Megamart grocery store. “Our total sales have increased this year by 20 percent since we added a pharmacy section to our grocery store. Clearly, the customer’s main concern is the convenience afforded by one-stop shopping. The surest way to increase our profits over the next couple of years, therefore, is to add a clothing department along with an automotive supplies and repair shop. We should also plan to continue adding new departments and services, such as a restaurant and a garden shop, in subsequent years. Being the only store in the area that offers such a range of services will give us a competitive advantage over other local stores.” 题库号码:44 提纲: 1.
总体销售额增加20%利润不一定也会相应增加 2.
销售额的增加不一定是由于增加了这个部门造成的 3.
以后是否还会有如此效果不一定。因为可能已经有企业提供更专业更优质的商品和服务。 1.
没有建立因果。sequence不能证明因果。不知道收入来自哪个section. 很可能是有其他的原因:很可能是pharmacy没有利润。利润来自其他的部分。比如食品等,质量提高,或者经济情况好,人们有更多的demand。 2.
销售额增加不一定是profit增加。 3.
错误类比:就算加入了pharmacy引起了收入提高,也不能说增加的clothing和其他也会引起收入。很可能人们不是因为convenience,而是对medicine的需要。很可能其他的,人们更愿意到special shops。 |
